Fix a squealing noise on a Toyota

If you drive a 2001-04 Camry, Highlander, Solara, or an ’04 RAV4 and you have a squealing noise or rattle coming from the engine compartment, this may solve your problem.

Toyota says the squealing noise usually happens when the engine is cold and that the issue is the automatic belt tensioner used in these 2AZ-FE engines. They have redesigned the part to eliminate the squealing noise. The new part number is 16620-28011. If your vehicle is still under warranty or extended warranty, you may get coverage for the part and labor. Read the fine print on your policy to see if it disclaims coverage for squeals. Sometimes a contract may exclude coverage for rattles, so make sure you describe the noise as a squeal and make sure your warranty company understands that Toyota has a Technical Service Bulletin on this part.

Get the BEST auto repair informationAlldatadiy.com and Eautorepair.net are the two best shop manuals—period! Unlike the cheaper Haynes and Chilton manuals that cover multiple year models, leaving the exact information you need to fix your car, these professional manuals cover your exact year, make, model. A subscription includes up-to-date the manufacturer’s technical service bulletins, step-by-step removal and installation instructions, illustrations, wiring diagrams, component locations, torque specifications, fluid types and capacities and maintenance schedules. Plus, they contain full trouble code descriptions and troubleshooting instructions.

Which one should YOU choose? If you’re tracking down a wiring issue, Eautorepair.net is the better choice. Eautorepair.net redraws factory wiring diagrams in color and includes the component, splice and ground locations right in their diagrams. That saves a lot of time because you don’t have to refer back to the component locator or circuit locations. Alldatadiy.com, on the other hand, uses the factory diagrams. So you have to refer to the factory legends to learn the identification symbols and then refer back to circuit diagrams to find the splice and ground locations. However, Alldatadiy.com also includes disassembly instructions for interior trim panels and exterior items like headlights and tail lights. If you need to dig into your doors, dash or console, Alldatadiy.com is the better choice because Eautorepair.net doesn’t any interior or exterior trim or body part removal.
